OMG.... What should we do now?

陰曆還是陽曆？

那這又是怎麼算的呢???

奶奶好像跟我奶奶差不多大耶

他們都牢記著自己的陰曆生日：雞年1月11日，雞年12月初9

然後上網查萬年曆，對照一下就知道陽曆啦

有恍然大悟的感覺

Are we going to change it officially?

i'm afraid that it can't be done in taiwan. they'll ask you to prove what your assertion is true.

How about birth certificate if they have one.....
